Specification of Letters Patent.

Application filed October 11, 1907.

Patented July 12, 1910.

Serial No. 396,948.

To all whom it may concern:

Be it known that I, RALPH W. STRAGHAN, a citizen of the United States,residing at Brockton, in the county of Plymouth and Commonwealth ofMassachusetts, have in vented certain Improvements in Shoe- Forms,ofwhich the following description, in connection with the accompanyingdrawlngs, is a specification, like reference characters on the drawingsindicating like parts in the several figures.

This invention relates to shoe forms, followers and lasts, which areemployed for determining, preserving or restoring the shapes of bootsand shoes.

The invention applies more particularly to that class of shoe formswhich are made in two parts so connected that they may be relativelymoved to be easily inserted into or withdrawn from a shoe, and alsoadjustable in length so that one form may fit shoes varying in size.

An object of the invention is to provide ashoe form which may beconveniently and easily adjusted in length when desired, which is ofmore simple construction than those heretofore in use and which can beeasily and cheaply manufactured.

In the drawing, showing a preferred form of the invention, Figure 1 is aView in side elevation of the form; Fig. 2 is a partial plan Viewshowing the heel part in horizontal section.

In the figures of the drawing, 1 represents a forepart and 2 a heel partwhich is adjustably connected to the forepart by means of anintermediate member 4. The forepart is provided with a slot at its rearend in which is inserted one end of an intermediate member 4, saidmember 4 being hinged to the forepart by a pin 6, arranged in a trans-Verse passage in said forepart. The heel part is provided with alongitudinal passage 8 formed to receive the member 4. As shown in thedrawing, the forward part of the member 4 is flattened, while the rearportion is cylindrical in transverse section. The forward part of thepassage 8 is substantially the same in section as the flattened part ofthe intermediate member, so that the heel part is held from turning uponsaid memer. The rear portion of the member 4 is provided with a seriesof lateral notches 10, arranged at intervals.

A horizontal cavity 12 is provided in the heel part intersecting thelongitudinal passage 8. In the cavity 12 a plug 14 is arranged, whichmay conveniently be composed of wood with a metal plate 16 secured inits inner end, said plate 16 having a slot 18 through which the member 4extends. As is shown in Fig. 2, the heel part 2 is normally held frommovement upon the member 4 by engagement of the plate 16 with one of thenotches 10. A spring 20 is arranged in the end of the cavity 12 to holdthe plug in engagement with said notches.

To prevent the heel part 2 from being accidentally removed from themember 4, a stop is preferably provided to limit rearward movement ofthe heel part upon said member. In the construction shown the forwardpart of the member 4 is provided with a slot 22, and a pin 24 carried bythe heel part is arranged in said slot. The heel part is provided with ahandle 26 for use in manipulating the form.

In the use of the form shown in the drawings, when it is desired to varythe length of the form the plug 14 is pushed inwardly to disengage itfrom the member 4 and the heel part may then be moved upon said memberto the point desired. It will be seen that when the plug 14 isdisengaged from the member 4 there is considerable liability of the heelpart being moved too far rear-- wardly and the provision of the stop 24prevents the accidental dismembering of the form which would result fromsuch a movement. The plug 14 as shown in Fig. 2 in its outermostposition is flush with the side of the heel part, so that in the use ofthe form the portion of the heel part which engages the shoe is smoothand uninterrupted.

Having described my invention, what I claim as new and desire to secureby Letters Patent of the United States is 1. A form, or tree, forinsertion in boots or shoes, having in combination, a forepart, a memberpivotally connected at one end to the forepart and provided at its otherend with a series of notches arranged at intervals in its length, saidnotches being formed in one side of the member, a heel art provided witha longitudinal passage 'ormed to receive said member and having ahorizontal cavity intersecting said passage, a plug arranged in saidcavity and provided wlth a slot to receive said member and arranged tohold the heel part from movement upon said member by engagement withsaid notches, and a spring arranged in said cavity between said plug andthe bottom of the cavity to hold the plug in yielding engagement withsaid member.

2. A form, or tree, for insertion in boots or shoes, having incombination, a forepart, a member pivotally connected at one end to theforepart, having at its other end a series of square notches in one sidearranged at intervals longitudinally thereof and provided with a slotintermediate its ends, a heel part provided with a longitudinal passageformcd to receive said member and having a horizontal cavity arranged tointersect said passage, a plug arranged in said cavity having a slot toreceive said member and adapted to hold the heel part from movement fromsaid member by engagement with said notches, the notches opening towardthe 20 ried by the heel part and arranged in the 25 slot of the memberto limit movement of the heel part upon said member.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
